Hi Hostis,
You need to ensure that any view that you want to work in offline doesn’t reference the entities that are not offline-enabled. For example, assuming Account is in the offline profile, then an Account view that references the primary contact when Contact is not in the profile will not be available.
You could refer to the Tips when configure D365 Mobile Offline:

In addition , there's also one known issue that Views are not supported for the following entities in offline mode:
- Email
- Task
- Appointment
- Fax
- Phonecall
- Letter
- Serviceappointment
- Campaignresponse
- Campaignactivity
- Recurringappointmentmaster
- Socialactivity

Hope the above helps.
